Rucksack

ABSTRACT

A knapsack or rucksack for providing leaning support for a wearer. The inventive rucksack or knapsack includes a back-wall and a bottom-wall formed of a rigid frame of a generally L-shape wherein a first leg of the frame supports the back-wall and a second leg supports the bottom-wall. The L-shape frame allows a user to lean against the back-wall of the rucksack or knapsack when the bottom-wall is on a support surface such as a floor.

BACKGROUND OF THE INVENTION

[0001] The present invention relates to rucksacks or knapsacks of the type carried on the back of travelers.

[0002] The prime object of the invention is to improve the structure of conventional rucksacks so that it becomes useful for the traveler as a back-rest.

SUMMARY OF THE INVENTION

[0003] To this end there is provided according to the present invention a rucksack comprising a back-wall and a bottom-wall characterized by a rigid frame of a generally L-shape having a first leg supporting the back-wall and a second leg supporting the bottom-wall thereof.

[0004] Preferably, there is provided a flap foldable between a first position wherein the flap overlaps the back-wall exteriorly, and a second position wherein the flap extends in the plane of and in a direction away from the bottom wall, thus enabling the rucksack to serve as a back-rest for one sitting of the flap in the second position thereof.

[0005] Optionally the rucksack may include an anti-weather cap configured to cover the head of the user in said sitting position.

[0015]FIG. 9 shows the frame and flap used in the embodiment of FIG. 7.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0016] As generally shown in FIG. 1, the rucksack generally denoted 10, which may otherwise be of any conventional design and shape, namely comprising a back-wall 12, a front-wall 14, a bottom-wall 16 and side- and top-wall 18 extending therearound.

[0017] Shoulder straps 24 and any other auxiliary components such as pocket 26 are included as in any conventional design.

[0018] However, the rucksack 10 is uniquely provided with a stiffening frame designated 20 preferably made of aluminum pipe. The frame 20 is generally L-shaped, the upright leg 20 a thereof extends along the corner formed between the back-wall 12 and the side- and top- wall 18. The horizontal leg 20 b of the L-shaped frame 20 extends the corner between the bottom-wall 16, the side-wall and the front-wall 14.

[0019] The frame can be simply inserted into the rucksack and secured by several stitches (not shown). It may also be overall covered by a cloth sheath.

[0020] The rucksack 10 further differs from conventional designs by being provided with a flap 30, made of canvas stuffed with upholstering material 31, can be positioned to extend in the plane and as an extension of the bottom-wall 16, as shown.

[0021] According to an additional aspect of the invention there is provided a cap 32 with tying strips 34. The cap is normally stored within a pocket closed by sipper 36.

[0022] In more detail now and with reference to FIGS. 2-6, it will be readily understood that the flap is normally partly stored within a pocket 34 prepared for that purpose (FIG. 3). When needed for use, the flap 30 is extracted from the pocket 34 (FIG. 4) and spread into the horizontal position (FIG. 5).

[0023]FIG. 6 vividly shows the mode use of the rucksack 10 as a firm back-rest while the user comfortably sits on the flap 30 thereby avoiding the rucksack from ”escaping” backwards under the force exerted thereagainst by the back of the user.

[0024] The embodiment of FIGS. 7-9 is designed to allow the frame-and-flap system to be removed or separated from the rucksack. Hence, rucksack 110 is provided with a double-wall structure and annexed to both the back-wall 140 and the bottom-wall 142, the latter being closeable by flap 144 with zipper 146 at three sides thereof.

[0025] The frame 120 with upright section 120 a and bottom section 120 b is enclosed within a common cloth sheath 148 to which the flap 130 is sewn along edge 150.

[0026] Thus provided is a neat and effective solution for travelers seeking a comfortable rest under field conditions at no extra cost of, e.g., carrying a choir or stool for that purpose.

[0027] While the above description contains many specificities, these should not be construed as limitations on the scope of the invention, but rather as exemplification of the preferred embodiments. Those skilled in the art will envision other possible variations that are within its scope. Accordingly, the scope of the invention should be determined not by the embodiments illustrated, but by the appended claims and their legal equivalents. 

What is claimed is:
 1. A rucksack comprising a back-wall and a bottom-wall characterized by a rigid frame of a generally L-shape placed within the rucksack having a first leg supporting the back-wall and a second leg supporting the bottom-wall thereof.
 2. The rucksack of claim 1 further characterized by a flap foldable between a first position wherein the flap overlaps the back-wall exteriorly, and a second position wherein the flap extends in the plane of and in a direction away from the bottom wall, thus enabling the rucksack to serve as a back-rest for one sitting of the flap in the second position thereof.
 3. The rucksack of claim 2 wherein the frame is integrally formed of bent-over metal pipe sections, both the first leg and the second leg being U-shaped.
